As a result , vulnerable ecological environment is showed with the ecological bearing capacity in middle reaches of hetian river . in the view of the features of landscape pattern in the middle reaches of hetian river , the landscape protection principles of development , harmonization and reality and ecological landscape construction principle including adapting nature , mutualism , adjusting ecosystem and meliorating function , local regulation and whole " harmonization are put forward A ，指出区域内生态环境质量在提高，但依旧无法脱离荒漠生态体系，是一种极其脆弱的生态环境。针对和田河中游地区景观生态的具体特点，提出了发展、协调、现实的景观保护原则以及适应自然、共生互利、调整结构，改善功能、局部控制与整体协调的景观生态建设原则，相应地制定出河流廊道建设、绿色植被建设以及绿洲建设的景观生态建设途径
Results came as follows : in this dissertation , we found that it was the smallness of the positive electrode capacitance that limits the performance of carbon based supercapacitors in alkaline electrolytes , and the performance could be meliorated if the active material loaded on positive electrode increased . activated carbon electrode was proved to have good capacitor performances in neutral electrolyte such as ammonium sulfate solution and ammonium nitrate solution , but a correlated problem is the corrosion of the metal current collector 本文通过考察活性炭电极在碱性电解液中的电极行为，指出活性炭电极在碱性溶液中正极性能较差是影响碳基超级电容器性能的重要因素，增大正极活性物质的载量能够使电容性能得到一定程度的改善，同时发现活性炭电极在硫酸铵和硝酸铵等中性电解液中具有优越的电极性能，但存在金属集流体的腐蚀问题。
The fourth chapter discusses management of the process of features construction , in this chapter , the author first pointed out some problem in the building and management of features construction of cities and towns in chongqing , then , in order to in meliorate the gross situation , the author brought forwards some ways such as city operation and illuminated how to use these ways 第四章论述对城镇风貌的建设与管理。本章首先指出目前重庆城镇风貌建设与管理中存在的问题，然后针对粗放型的建设与管理状况，提出城市经营等改善管理的方法并说明这些方法在重庆城镇风貌建构中的具体运用，最后归纳重庆城镇风貌建构的原则和程序。
Two - addition technique of flying ash and silica fume can meliorate durability of concrete ; air - entraining admixture possesses anti - freezing , descending ice point , and improving workability , and thereof it should be used in concrete . but controlling its dosage is very important to avoid strength loss 发现粉煤灰和硅灰的双掺技术能够显著改善混凝土的耐久性能，引气剂具备防冻抗冻、抗渗及提高负温混凝土工作性的优点，在负温混凝土中应该加大使用范围，但必须控制其掺量，确保强度损失较小。
By studying and learning the overseas experiences , the bus rapid transit with the chinese characteristics should be established and meliorated step by step with our urban traffic specific conditions to improve the running efficiency and the whole level of service of the public traffic , and then make the entire traffic environments better in essence 借鉴国外成功经验，结合我国城市交通具体情况，建立并逐步完善有中国特色的快速公交系统，以期提高公交运营速度与整体服务水平，进而从根本上改善整个交通环境。
The author programs for new design through microsoft visual basic and microsoft access , and applies the program successfully to actual system design , and in the end concludes a control strategy adapting the situation of china . the strategy is characterized by adding and meliorating a few of the equipments of the primary pump system , resulting in safe , efficient and economic operation mode , and lighting the workload at the same time 本文针对目前国内普遍采用的一次泵变流量系统存在的问题，吸收了国内外空调冷水变流量系统成功的控制方法的长处，提出了一种既适合中国国情，又经济可行的控制策略，其特点是，只需在现有的一次泵系统控制形式上增加和改进少量控制设备，就能使系统安全、高效、节能运行，并降低了空调冷水系统的能耗，减轻了运行管理人员的工作量。
Chapter 5 : the crucial part of this paper . first , the basic thoughtfulness about the planning of waterfront landscape spatial system in wuhan city and the planning mode are presented . then practical measures and approaches for meliorating it in waterfront planning and construction of wuhan city are introduced 第5章：是本文最重要的部分，探讨了武汉市城市滨水景观空间系统规划的基本思路及规划模式，并就前文指出的武汉市滨水区开发及现状滨水景观格局中存在的问题提出了相应的对策及改善途径。
The result of the experiments shows that the effects of compound pozzolanic and micro - aggregate have been produced when silica fume and slag were added into concrete together . and the stone enveloped with cement can meliorate distinctly the structure of the transition zone of interface , thus the strength of concrete is improved 试验结果表明：在混凝土中同时掺入硅灰和矿渣可以产生复合火山灰效应和微集料填充效应； “净浆裹石”搅拌工艺可以大大改善界面过渡区结构，从而提高混凝土的强度。
The researching work is combined with our actual project , and it will provide rational guidance in theory for our project in the future as more as possible . it is very useful to meliorate the surrounding on the navy vessels , and also helpful to develop new air - conditioner . i believe that this designed system has well prospect 本课题的研究，结合了实际工程项目的成功实施，在尽可能的情况下，为实际工程项目的进一步优化实施提供理论指导；并且对于开发新的环保、节能空调也有非常大的推广意义，相信本除湿制冷系统会有良好的应用前景。
